aipex-mcp-bridge

MCP bridge that connects AI agents to the AIPex browser extension via WebSocket.

Works with any MCP client that supports stdio transport — Cursor, Claude Desktop, Claude Code, VS Code Copilot, Windsurf, Zed, and more.

How it works

AI Agent (MCP client) ──stdio──▶ aipex-mcp-bridge ──WebSocket──▶ AIPex Chrome Extension

The bridge starts a WebSocket server on localhost:9223 (configurable) and communicates with your AI agent over stdio using the MCP protocol. The AIPex extension connects to the WebSocket server to expose browser control tools.

Quick start

1. Configure your AI agent

Add the following to your agent's MCP configuration:

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

Claude Code:

claude mcp add aipex-browser -- npx -y aipex-mcp-bridge

VS Code Copilot (.vscode/mcp.json):

{
  "servers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

Windsurf (mcp_config.json):

{
  "mcpServers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

2. Connect AIPex extension

1. Open Chrome → AIPex extension → Options page
2. Set WebSocket URL to ws://localhost:9223
3. Click Connect

Your AI agent can now control the browser through AIPex.

Options

npx aipex-mcp-bridge [--port <port>]

| Option | Default | Description | | ----------------- | ------- | ---------------------------------- | | --port <port> | 9223 | WebSocket port for AIPex extension | | --help, -h | | Show help message | | --version, -v | | Show version |

Custom port example

{
  "mcpServers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge", "--port", "8080"]
    }
  }
}

Requirements
